Compilation with: (base) $ gfortran -c b12.f90 f951: internal compiler error: in generate_finalization_wrapper, at fortran/class.c:1618 Please submit a full bug report, with preprocessed source if appropriate. See for instructions. As a worjk around, adding a dummy attribute clears the ICE. The workaround was motivated by report Bug61767. (base) $ gfortran -v Using built-in specs.
